Application filed April 26,

inserted a cushion member which may well be formed of a layer of soft sponge rubber. Preferably the cushion member is cemented or otherwise fixed to the upper lamination, but is unattached to the lower lamination except at its extreme forward end so that the upperlamination and cushion member are free to yield and to conform to the foot unhampered by attachment to the shoe upper or outersole, which, in the case of an innersole, are both fixed to the lower lamination. The forward end of the cushion member is skived'to a thin edge along a curved outline conforming somewhat closely to the curve of the metatarsal arch so that in the completed innersole a rounded projection is formed on its'upper face between its side edges to furnish aproper support for this arch.

' For a more complete understanding of this invention, reference may be had to the accompanying drawings in which Figure 1 is a perspective of an innersole blank cut to receive the cushion member.

Figure 2 is a perspective of the cushion member.

F igure 3 is a top plan of theblank and cushion member assembled.

Figure 4 is a longitudinal section through awelt shoe showing an innersole constructed according to this invention, the bones of a foot being shown.

Referring to these drawings, at l is shown an inner sole blank which is first split from its heel end to form lower and upper laminations 2 and 3. This split portion extends forwardly. of the shank and itscentral portion is extended further than its side portions, as shown by the dotted line at 4,'or it may be split substantially uniformly as shown by the dotted line 5 and later cemented together over that portion between the lines 4 and 5 this being done for ease in manufacture.

In place of splitting the innersole, it, might SHOE.

be formed with less ad vantage from two sole shaped blanks cemented together over their substantially the line in-.

upper layeradjacent to the concave central the line 4 is perforated at inter portion of vals. This not only acts as a ventilating means for the sole, but: also serves to weaken the central portion of the upper lamination so that it may be distorted upwardly as will later appear.

At 10 (Figure 2) is indicated a cushion memlier formed of a sheet of soft sponge rubber. This in practice may be approximately a quarter of an inch thick when uncompressed. The forward end of [this cushion member is skived to a thin edge as shown at 11 and is given a contour substantially that of the dotted line 4 of Figure 1. The remainder of the outline of-the cushion member conforms to the outline of the sole extending to the heel end. This cushion member'is in serted between the laminations 2*and3 and is preferably cemented to the top lamination 3 only, being entirely free from the lamination 2, except at its extreme forward end where it may be cemented thereto or-by the attachment of the upper lamination to the lower at the forward end of the split portion.

l/Vhen the sole is in the shoe this cushion member 10 acts to press upwardly the material of the upper. lamination to form a rounded projection at the forward end of the cushion member which acts to support the metatarsal arch of the foot. The cushion material being soft permits the upperlamination to yield to the pressure of the foot, thus causing it to conform automatically to the longitudinal arch and the transverse arch along the cuneiform bones.

The position of the arches of the foot with relation to the cushion portion of the sole. is indicated in Figures 3 and 4 where the phalanges are indicated at 20 and the metatarsals at 21. It will .be seen that the forward protuberance of thesole at the forward endof the cushion member comes beneath the metatarsal bones and conforms, more particularly when the weight of the wearer comes thereon, to the metatarsal arch, while the portion of the sole to the rear of this arch is depressed As shown the heel end 0 tion is also perfo ure 1, sometimes this When this innerso McKay shoe, tion is attach parts of theshoe in the usual man where the laminations occur the lowe ched. For example,
